Lecidella carpathica
Lecidella carpathica is a species of crustose lichen in the family Lecanoraceae. It was formally described as a new species in 1861 by the German lichenologist Gustav Wilhelm Körber.
Three secondary metabolites that occur in this species, hopane-6α,22-diol, brialmontin, and atraric acid, inhibit the enzyme protein tyrosine phosphatase 1B. This enzyme is a therapeutic target for diabetes treatments and plays a major role in negative regulation of the insulin signaling pathway.
